1. Key Lime Pie Recipe (Yield: 10 Servings)
Ingredients
Graham Cracker Crust
- 1 1/2 cups graham cracker crumbs
- 1/3 cup granulated sugar
- 6 tbsp butter, melted
Key Lime Filling
- 28 oz sweetened condensed milk
- 1/2 cup light sour cream
- 3/4 cup key lime juice
- Zest from 2 regular limes or 4 key limes
Whipped Cream Topping
- 1 cup heavy whipping cream
- 1/2 cup powdered sugar
- 1 tsp vanilla extract
Instructions
Preheat your oven to 350°F (175°C). Lightly grease a 9-inch pie dish and set it aside.
Begin by preparing the graham cracker crust. In a medium mixing bowl, combine the graham cracker crumbs and granulated sugar. Pour in the melted butter and stir until all the crumbs are evenly moistened and resemble wet sand.
Transfer the crumb mixture to the prepared pie dish. Using the bottom of a measuring cup or glass, firmly press the crumbs into the bottom and up the sides of the dish to create an even crust.
Place the crust in the preheated oven and bake for 8 to 10 minutes. The crust should appear lightly golden and set. Remove it from the oven and allow it to cool while preparing the filling.
In a large mixing bowl, add the sweetened condensed milk and sour cream. Whisk until smooth and fully combined.
Pour in the key lime juice and add the lime zest. Continue whisking until the mixture becomes smooth and slightly thickened. The acidity of the lime juice will naturally help thicken the filling.
Pour the filling into the cooled graham cracker crust. Use a spatula to spread it evenly and smooth the top.
Place the pie into the oven and bake for 12 to 15 minutes. The filling should be mostly set but still have a slight jiggle in the center.
Remove the pie from the oven and allow it to cool completely at room temperature. Once cooled, cover the pie and refrigerate for at least 4 hours. For the best texture and easiest slicing, chill overnight.
When the pie has fully chilled, prepare the whipped cream topping. In a large chilled mixing bowl, combine the heavy whipping cream, powdered sugar, and vanilla extract.
Using an electric mixer, beat the mixture on medium-high speed until stiff peaks form. Be careful not to overmix.
Spread or pipe the whipped cream over the chilled pie. Create decorative swirls if desired for a more elegant presentation.
Garnish with additional lime zest or thin lime slices if desired. Slice and serve chilled.
Store any leftovers covered in the refrigerator for up to 4 days.
2. Tips for Perfect Homemade Key Lime Pie
Allow the crust to cool before adding the filling. A hot crust can affect the consistency of the filling and make assembly more difficult.
Use freshly squeezed key lime juice whenever possible for the most authentic results.
Chill the pie thoroughly before serving. Adequate chilling time helps the filling set properly and improves the texture.
For neat slices, dip a sharp knife into warm water and wipe it clean between cuts.
If using regular limes instead of key limes, the pie will still turn out delicious and maintain a bright citrus flavor.
Use a glass or ceramic pie dish for even baking and easier serving.
Prepare the pie a day in advance when possible. Overnight chilling often improves the texture and makes serving easier.
3. Frequently Asked Questions
Can I use bottled key lime juice?
Yes. Bottled key lime juice can be a convenient substitute when fresh key limes are unavailable. Many grocery stores carry bottled versions specifically labeled as key lime juice.
Why is my key lime pie filling not firm enough?
Insufficient chilling time is the most common reason. The pie needs several hours in the refrigerator to fully set before slicing.
Can I freeze key lime pie?
Yes. Key lime pie freezes well. Wrap it tightly and freeze for up to 2 months. Thaw overnight in the refrigerator before serving.
What is the difference between key limes and regular limes?
Key limes are generally smaller and contain more seeds than regular limes. They are commonly used in traditional key lime pie recipes and provide a slightly different citrus profile.
Can I make the pie without the whipped cream topping?
Absolutely. The pie is delicious on its own, though the whipped cream adds a decorative finish and complements the dessert nicely.
